- vrlhe presenty invention relates to improvements in self-adjustinganti-rattle dovetails, particularly for automobile doors, an lobjectbeing to provide a device of this character l socket member is vprovidedas an attachment The present arrangement greatly simplifies assembly andprovides a permanent, reliable and accurately positioned socket. It islproposed in the present embodiment to provide a Vdovetail in which thesocket member is'provided with laterally adjustable resilientlysupported dovetail members adapted to have a Ywedge member engagedbetween them, the respective dovetail members being supported againstVertical movement, and which are adapted to retain the door againstvertical vibration,and compensate for wear,llateral movement,-andvariations in thevertical and lateral lalignment of the door.

A y A. still further obj ect is to provide a device in whichthe'dovetaill members will be protected from eXcessivewear and breakage,and may be made of a self-lubricating substance, such as fibre, bakeliteor the like, to the end that the device will have a long life', and thenecessity for lubricating the same'will be the door showing the wedgemember mounted thereon, the door being shown' in `dotted e jlines,"whilethe wedge-membeIi-is shownn full lines.

Referring to the drawing, the device, according to the presentembodiment ofl'theinventon, comprises a ,socket element incorpon ratedas a Astructural part` of the metal post of the door frame 10, and awedge element adapted to be secured to the edgeof the door vthe socketupon closing of the door. y K The metal post 10 ofthe'door frame isbentl along a vertical line to forma right angular corner, against whichthe door closes. A

lrearwardly converging opening 12 is cut posed iny parallel vrelationand its end; edge vertically disposed.

' The inner or box part .ofA the' sock-et'V is i formed from sheet metaland as shown in Fig. 5 comprises a rectangular portion 13 having wallflanges 14, bent from its upper and lower and rear edges, and outwardlyextending base lianges l5 bent from the upper,` and lower wall flanges.A pair of inwardly bent llugs 16 rare struckfrom the rear wall 'flangefor supporting the ends of the springs, presently to beV more fullyreferred to.

socket as- The box thus provided is somewhat wider than the opening 12and upon its forward edge there is provided a projecting lip 17 of suchdimensions as to enter the opening 12 to seat upon its vertical edge,and to project slightly beyond it, lthe projecting portion being bent ata slight angle. When so engaged the base flanges lie flat upon ltheinner surface of the post, their forward edges abutting the innersurface of the flange of the post, and in this relation the box issecured by spot-welding the base flanges to the post at suitable points,as indicated at 18, Fig. 8.

It will be seen that the lip, with its angularly bent edge accuratelypositions the box upon the post so that it may be secured in its properrelation with the greatest facility, and in the assembled relationprevents distortion ofthe box through strains imposed upon it. The liphas the further advantage of forming a guide surface for the Wedgeelement as it enters the socket.

A pair of opposed block members 19 of generally rectangular shape aredisposed within the casing, these blocks `having flat parallel surfaces20 adjacent the inner ends in-sliding'engagement with each other, andcooperating with the upper and lower parallel 1walls of the casing toprevent ver- Atical displacement of the blocks. Inclined slightlyyarcuate faces 21 extend from the flat faces 2O to the forward ends ofthe blocks in diverging relation to each other. Pockets 22 are providedin the rear walls of the blocksv within which are engaged coil springs23 positioned upon the lugs 16 of the casing, and which press the blocksforwardly against the flange of the post, as shown in Fig. 6, whilepermitting the blocks to be forced laterally inwardly as shown in Fig.10. In both positions the inclined faces 21 are projectedy into theopening. 12. l Y

p The blocks may be assembled within the casing through the opening 12,this being done conveniently by first inserting one of the blocks andits spring, and then inserting the other block and its spring,rpressingthe first block inwardly while the second block is being inserted. Theblocks may be of any suitable material, and because of the protectionagainst breakage afforded by the casing, may be of fibre, bakelite, orother suitable squeak preventing, self-lubricating material.

`The wedge member comprised an attaching base 24 having screw holes 25,and a rigid projecting -wedge-shaped projection 26, having flat inclinedsides 27, substantially corresponding to the inclination of the dovetailblocks. Y

The slightly arcuate shape of the inclined surfaces of the blockspermits firm engagement of the wedge member irrespective of Y slightvariations in the vertical alignment of the door. Obviouslythisarrangement may be reversed, if desired, and-the inclinedsur-V facesof the Wedge member made slightly arcuate, the inclined surfaces of theblocks being flat.

In Figs. 12 and 13 we have shown a modification in which the blockmembers 19 are adapted to be assembled and held in the box casing beforethe latter is attached to the post. For this purpose lugs 28 are formedupon the forward edges of the upper and lower wall flanges 14, beingbent inwardly so that their forward surfaces are flush withsaidforwardedges of the wall. In the forward ends vof the block membersthere are provided .pockets 29, of corresponding depth to the metalthickness of the lugs, and within which the latter engage with ktheforward end surfaces of the blocks in flush relation to the forwardedges of the box, `so that the same may be assembled against the flangeof the post in exactly the samemanner as the box illustrated in Fig. 5.The engagement of the lugs 28 in the pockets 29 not only retains theblocks against the outward pressure of the springs, but so interlockwith the pockets as to prevent displacement through the open side of thebox, thus permitting the box with the assembled blocks to be handled andshipped in quantities without danger of the blocks becoming displaced.

The operation is as follows When the door is in open position the blocksare projected forwardly against the flange of the post as indicated inFigs. 1 and 6.V vAs the door is closed the wedge member engagesbetweenjthe blocks, contacting therewith before the door is completelyclosed, the complete closure of the door causing the blocks to be movedlaterally against the pressure of -the springs which yhold the blockssnugly against the wedge member, while the inclination of the `engagingsurfaces is such that vertical pressure will not displace the blocks andcause vibration.

The door is provided with the usual latch not shown, which engagesbehind a striker on the door frame, and the-present device is such thatit permits the door to close sufliciently to allow the latch to operate,and thereupon jexerts an outward pressure on the door to force the latchbolt tightly against nthe striker. Upon release of thelatch the deviceexerts an opening pressure on the door. f V

Should the wedge member be out of alignment with the socket, due tosagging of the door or inaccurate mounting of the wedge member, theindependent movement of the respective blocks will permit them to adjustthemselvesto the wedge surfaces and perform their' cooperative retainingfunction.

We haveillustrated and described a pre- 'ferred and satisfactoryembodimentof the invention, but 4it will be obvious that changes may bemade therein,`within the spirit and 1 -Y scope thereof, as deiined inthe appended claims.

Having thus described our invention what We claim and desire to secureby Letters Patent is l. In an anti-rattle device for doors, thecombination with a door frame metal post forming an angular corner andhaving a Wedge receiving opening, of a casing adapted to be engaged atthe inner side of said post and having a projecting lip portion adaptedto engage in said opening to accurately position said casing withrespect thereto, Wedge engaging means disposed in said casing, and a WedUe member adapted to be engaged there- With through said opening and tobe guided by said projecting lip. p
